What are invisible grills?
Safety without sacrificing beauty or airflow.
Invisible grills — also called cable grills or frameless grills — use tensioned stainless steel cables stretched vertically or horizontally across your balcony, window or terrace opening. From a normal viewing distance, the cables are nearly invisible, giving you complete safety without the obstructed, closed-in feeling of traditional iron grills.
KSR Safety Nets uses SS316 marine-grade cables — the same quality used in coastal marine applications — that resist corrosion, UV damage and the temperature extremes of Bengaluru's climate. Each cable is tensioned to exactly the right specification for safe, long-lasting performance.
Why choose invisible grills?
Virtually Invisible
3–4mm cables are nearly impossible to see from a normal distance, preserving your view completely.
Extremely Strong
Each SS316 cable has a breaking strength of 300–500kg — far stronger than traditional grills.
Full Airflow
Cables allow complete natural ventilation — fresh air flows freely at all times.
Rust-Proof
SS316 marine-grade steel resists rust and corrosion even in high-humidity environments.
Low Maintenance
No painting, no oiling — just occasional cleaning. Our AMC covers annual tension checks.
Quick Installation
Most balcony grill installations are completed in 4–8 hours with minimal disruption.

Frequently asked questions
Yes. Each SS316 cable has a breaking load of 300–500kg when properly tensioned. The cables are anchored into concrete or RCC structural members. The system as a whole is tested to withstand accidental impact loads far exceeding what a child or adult could apply. They meet and exceed standard safety requirements.
Standard cable spacing is 80–100mm (8–10cm) for general use. For child safety and pet safety applications, we reduce the spacing to 50–60mm to prevent any possibility of a small child or cat slipping through. Our team recommends the appropriate spacing during the site inspection.
Our SS316 marine-grade cables are specifically designed for high-humidity, outdoor environments. They are used in coastal and marine applications worldwide. In standard Bengaluru conditions, they will not rust or corrode for well over 10 years with minimal maintenance.
Yes. We install invisible grills in apartments across Bengaluru every day. We work cleanly, respect your neighbours and minimise dust and disruption. Most apartment installations require anchoring into the slab or beam, which our team handles with appropriate tools and clean finishing.
